HEELING-MACHINE.

Specification of Letters Patent.

Patented May 2c, 1919.

Application filed January 13, 1916. Serial No. 71,899.

tion, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This'invention relates to heeling machines and is designed to provide mechanism whereby a heel blank may be attached and at the same time pricked for the reception of hob nails or similar wear-resisting devices.

To this end, an important feature of the invention consists in a removable tool carrying plate for heeling machines having two series of tools, one comprising a gang of drivers and the other comprising a gang of awls, the awls and drivers being correspondingly arranged in the plate in horseshoe shaped figures, and the awls being longer than the drivers. A tool block provided with such tools may be used to advantage in heeling machines of any desired type. In operation the drivers act to drive the attaching nails substantially flush with the outer surface of the heel blank While the ends of the awls enter the blank and form holes for the reception of the nails to be driven later.

In shoes having heels with hob nails it is desired to insert the hob nails so that their heads shall be disposed adjacent to or covering the ends of the attaching nails. To this end another feature of the invention consists in a tool block having a gang of drivers arranged in a horseshoe-shaped figure and a gang of awls similarly arranged and disposed adjacent to the drivers.

These and other features of the invention will be best understood and appreciated from the following description of. a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which,-

F1 re 1 is a view in front elevation,

part y in section, of portions of a lightning,

nailing machine having the present invention embodied therein;

Fig. 2 is a view in perspective'of the tool a block, and v Fig. 3 is a view in perspective of an at tached heel with some of the hob nails driven.

The frame of the machine 2 is provided with a stationary die plate 4: having at its center vertical awl and driver passages. Beneath the die plate is located a jack 6 upon which is to'be positioned the-shoe to be heeled. The jack is movable upwardly toward the die plate to press the heel upon the sole of the shoe preliminarily to the attaching operation. The mechanism for elevating the jack is not shown herein as it' forms no part of the present invention.

The frame 2 is provided with vertical bearings for side rods 8 which carry a cross head 10 at their upper ends. Beneath the cross head is detachably secured a tool block 12 in which are set the awls and drivers.

The drivers shown in Fig. 2 are arranged in a horseshoe-shaped figure with three drivers set in a line parallel to the front edge of the plate, and are of the usual construction. The awls 16 are of the same diameter as the drivers and are arranged in a horseshoe-shaped figure within the outline of the driver gang. The awls are somewhat longer than the drivers and have tapering points.

In the operation of the machine the shoe, upon a last 24, is placed upon the jack 6 and the heel 20 is positioned beneath the die plate 4. The heel and shoe are then pressed together and the cross head 10 lowered. In. this operation the drivers 14: drive the attaching nails, which have previously been supplied to the die plate, through the heel 20 and into the sole of the shoe leaving the outer ends of the attaching nails substantially flush with the tread face of the heel. At the same time the awls enter the tread face of the heel and form holes therein of a depth equal to the excess length of the awls over the drivers, as shown in Fig. 1. After the cross head has been elevated the shoe is removed with the attached heel and subsequently hob nails 26 are driven into the holes in the heel formed by the a-Wls.

The appearance-0f the finished heel Will be apparent fronrEig; 3 in which the endsof' be attached has been referred to as a heel blank and by this term it is intended to include either a complete heel or a section or deck of a heel. It will further be apparent that the avszl holes may be utilized for other purposes than for'the reception of hob nails withouit in any Way modifying the novel construction herein disclosed and claimed.

Having thus described my" invention, I claim as new and desire'tosecure-by Letters Patent 4 1. In a heeling machine, a detachable tool carrying-plate having aseries of drivers arranged in a-hiorseshoe shaped figure and a series of longer avvls correspondingly arrangedvi-ng the plate-within the outline of the drivers.

2. In a heeling machine, a; detachableplate having set therein a series of pointed awls arranged 111 a horseshoe-shaped figure and having; also set therein, av series of.

horseshoe-shaped figure and a. series. of.

longer aWls also set in the plate in an outline corresponding to that of the drivers, and means for eflectlng operative movement of said tool carrying plateptoa point where the-ends. of" the drivers are snbstantially in the plane of: theh eel' engaging face of. the

dieplate andv the points of the; aWls project beyond said facehi-nto a hieel located in engagement there-Withe v In testimony whereof I' haveasigtned' my name to this specification.
